First thing.. Are there any symptoms going on other than a extra bolt laying in the oilpan?
If no and there are no noises then its not from the lower end. The engine would not be running good and quietly with a main cap/bolt missing.
Next is to get it out and find what type bolt it is. Since you say its a fine thread it could be from a oil tensioner or a cam adjustment or locator. Will take a lot of looking around for the same type bolt.
Really P1 should be get teh bolt out first thing and not drive it till you make sure its not from the engine. Suprising that the dealer is not making a issue with Ford about seeing where it came from. Might be smart to get with Crystal here the service rep and see what she can do for you. If it were me I not drive it till I fond out what/where it came fromm.
